Abstract
In the present invention, by superimposed for the end of rubber component and when being joined together, can engage with the bonding area less than the bonding area that tradition uses by increasing bonding area. The present invention is a kind of for making the one end in upside (71) of rubber component (tire member of formation) (70) and superimposed and then engage the joint device of the end of rubber component (70) in the other end (72) of downside. The backer roll (disk shape roller) (45) rotated around tilting axis is rolled when compressing superimposed upper side end (71) of rubber component (70), and upper side end (71) is stretched by the shearing force now produced, which increase the bonding area between both ends (71,72).
Description
Technical Field
The present invention relates to a joining device and a joining method of rubber members, in which ends of the rubber members abut against and are joined to each other.
Background
There is known an engagement device provided in a tire building apparatus, which is configured to: superimposing end portions of a rubber member such as a tire constituent member in the up-down direction on a building drum, that is, superimposing in the up-down direction on the building drum in a state where one of the end portions is positioned radially outside the tire building drum and the other end portion is positioned radially inside the tire building drum; pressing a pressing roller against the overlapping portion; and joining the end portions together (for example, see patent document 1).
Fig. 9 is a perspective view schematically illustrating the principle of such engagement of the tire constituent member.
In this conventional joining apparatus of tire constituent members, a tire constituent member 100 made of a rubber material and having a predetermined length is wound around a molding drum in a state where its end portions 101 and 102 are superposed on each other in the up-down direction, and a pressing roller 110 rolls on and presses the superposed portion. This enables the ends 101 and 102 of the tire constituent member 100 to be joined together with the adhesiveness of the unvulcanized rubber, thereby forming a cylindrical body such as a carcass ply.
In such a case where both end portions of the tire constituent member are superposed and the superposed portion is pressed from above by the pressing roller 110 to join the superposed portion, it goes without saying that the smaller (or narrower) the amount of superposition (joint area) is, the lower the joint strength of the superposed portion is. Therefore, there is a problem that a required bonding strength cannot be maintained unless a certain bonding area is secured.

Disclosure of Invention
Problems to be solved by the invention
The present invention has been made in view of the conventional problem occurring when the ends of a rubber member having a predetermined length are joined together, and an object of the present invention is to enable joining with a required joining force (or adhesive force) by increasing the joining area at the time of joining even in the case where the joining area, in which the joining strength cannot be maintained only by overlapping both ends of the rubber member and pressing a pressing roller against the overlapped portion as in the conventional approach, is small.
Means for solving the problems
One aspect of the present invention is a rubber member joining apparatus for joining overlapping ends of rubber members in a state in which one of the ends of the rubber members is overlapped on an upper side and the other end is on a lower side, the apparatus comprising: a pressing roller that rotates about an inclined axis that is inclined with respect to an end surface of the rubber member; a member for pressing the rolling surface of the pressing roller against the overlapped upper end of the rubber member; and a moving unit for rolling a rolling surface of the pressure roller in a state where the rolling surface of the pressure roller is pressed against the upper side end portion of the rubber member, wherein the upper side end portion is extended and joining is performed after increasing a joining area between the end portions to be joined by rolling the rolling surface of the pressure roller while pressing the rolling surface of the pressure roller against the upper side end portion of the rubber member.
Another aspect of the present invention is a joining method of a rubber member for joining overlapped ends of the rubber member in a state where one of the ends of the rubber member is overlapped on an upper side and the other end is on a lower side, the method including the steps of: pressing a rolling surface of a pressing roller against the overlapped upper-side end portion of the rubber member, wherein the pressing roller rotates about an inclined shaft inclined with respect to an end surface of the rubber member; and rolling the rolling surface of the pressure roller in a state where the rolling surface of the pressure roller is pressed against the upper side end portion of the rubber member, wherein the joining is performed after the upper side end portion is extended and a joining area between the end portions to be joined is increased by pressing the rolling surface of the pressure roller against the upper side end portion of the rubber member and rolling the rolling surface of the pressure roller.
ADVANTAGEOUS EFFECTS OF INVENTION
According to the present invention, even in the case where a required bonding force cannot be obtained by a conventional pressure roller that bonds a rubber member by overlapping end portions of the rubber member with each other and pressing the overlapped portion from above, the rubber member can be bonded with the required bonding force by increasing the bonding area.

Detailed Description
A joining device according to an embodiment of the present invention will be described with reference to the accompanying drawings.
First, a description will be given of a pressure roller (a disk-shaped roller in the present embodiment) to be used in the present bonding apparatus.
Fig. 1 shows a disk-shaped roller, in which fig. 1 (a) is a perspective view thereof and fig. 1 (B) is a front view thereof. Fig. 2 (a) is a plan view of the disc-shaped roller, and fig. 2 (B) is a side view of the disc-shaped roller when viewed along a direction perpendicular to a line L1 in fig. 2 (a).
As shown in fig. 1 (a), the disk-shaped roller 45 has a rolling surface 45b, and the rolling surface 45b is inclined toward the center of the disk-shaped roller 45 and rolls on an upper end 71 and a lower end 72 of the rubber member, that is, the tire constituting member 70 in the present embodiment, which are overlapped in the vertical direction. The disk-shaped roller 45 is preferably formed in a truncated cone shape including upper and lower flat surfaces.
As shown in fig. 2 (B), the disk-shaped roller 45 is rotatably supported by a roller shaft 46 via a bearing 47, and the roller shaft 46 is a tilt shaft fixed to a support 45a of a joining device described later.
As shown in fig. 2 (a), the roller shaft 46 is arranged: in plan view, inclined at a predetermined inclination angle θ 1 toward the joining end 73 with respect to the traveling direction of the roller 45, and arranged: is inclined forward at θ 2 with respect to the upper end portion 71 of the tire constituent member 70. The rolling surface 45b of the disc-shaped roller 45 has a rough surface, and a plurality of projections and recesses or a plurality of projections and recesses are formed on the entire rough surface by a hob or the like.
When a joining device provided with a disk-shaped roller 45 described later is moved, the disk-shaped roller 45 rolls around the roller shaft 46 with the inclined rolling surface 45b pressed against the upper end 71 of the tire constituting member 70. The disk-shaped roller 45 is arranged to be inclined at θ 1 with respect to the traveling direction ((a) of fig. 2) and at θ 2 with respect to the surface of the end portion 71 ((B) of fig. 2), so that when the disk-shaped roller 45 is moved while being pressed against the end portion 71 by the engaging means, the disk-shaped roller 45 abuts against the end portion 71 along a line L1 in (a) of fig. 2 while rolling to apply a shearing force S toward a direction perpendicular to the line L1.
When a shearing force S acts on the end portion 71 of the tire constituent member 70, the end portion 71 made of a rubber material extends, and accordingly the joining (bonding) area where the end portions 71 and 72 are superposed on each other is increased, and joining is performed with the increased joining area.
Therefore, even in the case where the required joining strength cannot be obtained only by pressing and rolling the cylindrical roller on the upper end portion 71 in a state where the end portions of the tire constituent member 70 are superposed on each other as in the conventional approach, the required joining strength can be obtained by using the present disc-shaped roller 45. Further, in the case where the margins for overlapping of the end portions 71 and 72 before joining are the same, a large joining force can be obtained.
The joint surface of the disc-shaped roller 45 is subjected to the surface roughening treatment, and therefore, when the disc-shaped roller 45 is pressed against and rolled on the tire constituent member 70, a larger shearing force S can be generated in the end portion 71 abutting against the joint surface by the frictional force of the end portion 71 and the joint surface, as compared with the case where the joint surface is not subjected to the surface roughening treatment, thereby enabling the end portion 71 to extend more effectively.
Further, setting the overlapping width between the end portions 71 and 72 to be smaller than the width (pressing width) of the rolling surface 45b of the disc-shaped roller 45 enables the end portion 71 to spread uniformly when the shearing force S is applied to the end portion 71 to extend the end portion 71.
The joining apparatus provided with the above-described disk-shaped roller 45 will be described below.
Fig. 3 is a front view schematically showing a main part of the configuration of the engaging device.
As shown, the joining device 1 includes: a cylindrical forming drum 2 having an axis held in a horizontal direction; and a pair of joining units 30 arranged side by side in the axial direction of the forming drum 2 for joining the tire constituent member 70. The joining device 1 further includes a moving means 10 for moving the pair of joining units 30 in the axial direction and the radial direction (the left-right direction and the up-down direction in fig. 1) of the forming drum 2. The moving member 10 is arranged above the building drum 2 along the outer circumferential surface of the building drum 2.
The building drum 2 is a support that supports the tire constituent member 70 to be joined at the time of building of the unvulcanized tire, is configured to be rotatable about its axis and to be stretchable and contractible by an air bag or the like provided at its outer periphery. The building drum 2 has a tire constituting member 70 wound around at a predetermined position of the outer periphery thereof by a length corresponding to one rotation of the building drum 2, and holds the cylindrical tire constituting member 70 coaxially. The building drum 2 is driven to rotate by a drive unit (not shown) connected thereto, a drive source such as a motor or the like provided in the drive unit, and a transmission mechanism of rotational power from the drive source, and the building drum 2 is capable of rotating the tire constituent member 70 at a predetermined rotational speed and stopping it at an arbitrary rotational angle.
The tire constituent member 70 is supplied from a supply unit (not shown) toward the forming drum 2, and the tire constituent member 70 is wound around the forming drum 2 in such a manner that the front end portion and the rear end portion of the wound tire constituent member 70 are arranged to overlap each other.
The tire constituent member 70, which is a known member per se, is formed by coating a cord made of an organic fiber or steel with an unvulcanized rubber. In the rubber on the surface, a plurality of cords (not shown) are arranged in parallel in such a manner as to extend in the axial direction of the forming drum 2.
The forming drum 2 supports both end portions 71 and 72 to be joined of the tire constituent member 70 in a state where both end portions 71 and 72 are overlapped with each other in the up-down direction, and the joining device 1 moves each of the joining units 30 on the end portions 71 and 72 overlapped in the up-down direction of the tire constituent member 70 along the joining end 73 between the end portions 71 and 72 to join the end portions 71 and 72.
The joining device 1 has a symmetrical configuration with respect to the center portion CL in the axial direction of the forming drum 2. Thus, hereinafter, a description will be given of a side with respect to the center portion CL.
The moving member 10 includes a guide rail 11 laid parallel to the axis of the forming drum 2, a threaded shaft 12 arranged parallel to the guide rail 11 and above the guide rail 11, a motor 13 arranged in such a manner that a rotary shaft 13A extends parallel to the threaded shaft 12, and a frame (not shown) on which the above members are mounted.
The moving member 10 rotatably supports the threaded shaft 12 by a frame, and has an endless belt 16 stretched between a driven pulley 14 fixed to the threaded shaft 12 and a driving pulley 15 fixed to a rotating shaft 13A of the motor 13. Further, the moving member 10 transmits the rotational power from the motor 13 to the threaded shaft 12 through the driving pulley 15, the belt 16, and the driven pulley 14, thereby rotating the threaded shaft 12 at a predetermined speed in both directions around the axis thereof.
The moving member 10 has a mounting bracket 17 mounted on the threaded shaft 12 and a piston-cylinder mechanism 18 fixed to a side surface of the mounting bracket 17 in a downwardly extending manner.
The mount 17 is driven by a screw transmission mechanism constituted by a ball screw or the like screwed with the screw shaft 12, wherein the screw shaft 12 penetrates the ball screw or the like. That is, the mounting bracket 17 has a screw hole and a guide hole through which the guide rail 11 slidably passes, and the mounting bracket 17 moves at a predetermined speed in both directions along the axis of the forming drum 2 while being guided by the guide rail 11 in conjunction with the rotation of the screw shaft 12.
The piston/cylinder mechanism 18 has a piston rod 18P that is telescopically movable in a cylinder 18S. The piston rod 18P is arranged above the building drum 2 in such a way as to extend towards the axis of the building drum 2. The piston-cylinder mechanism 18 advances or retracts the piston rod 18P, and thus causes the joining unit 30 fixed to the front end (lower end) thereof to move to or away from the tire constituent member 70. That is, the piston/cylinder mechanism 18 presses the disk-shaped roller 45 or the like fixed to the joining unit 30 against the upper end portion 71 to be joined of the tire constituent member 70 at a predetermined pressure or pulls the disk-shaped roller 45 or the like upward away from the upper end portion 71.
The engaging unit 30 includes a rectangular plate-shaped fixing member 60 fixed to the piston rod 18P of the moving part 10 and a rectangular frame 31 fixed to a lower surface of the fixing member 60. The frame body 31 is arranged along the joint portion of the tire constituent member 70. The joining unit 30 is moved integrally with the fixed member 60 and the frame 31 by the moving means 10.
Fig. 4 is a bottom view of the engaging unit 30 viewed in the arrow X direction in fig. 3 and shows a configuration of the frame body 31 side of the engaging unit 30 seen through the fixing member 60 (indicated by a broken line in fig. 4).
As shown in fig. 4, the joining unit 30 has, in the frame 31, a float prevention roller 32, a zipper roller (zipper roller) 40, and a disk-shaped roller 45 serving as a pressure roller, which are arranged in this order from the front side (left side) toward the rear side (right side) in the joining direction. Further, a small-diameter side pressing roller (preferably having a ring shape) 48 as another pressing roller is fixed adjacent to (on the lower side in fig. 4) the disk-shaped roller 45. Further, a rear pressure roller (in the present embodiment, a ring roller) 50 as a further pressure roller is disposed rearward of the disk-shaped roller 45.
The floating preventing roller 32 and the zipper roller 40 are supported by the support 32a and the support 40a, respectively, in a manner rotatable about their axes, and the supports 32a and 40a are each connected to the fixing member 60 by a force applying means described later. Similarly, the support 45a of the disk-shaped roller 45 is connected to the fixing member 60 by a force application means. On the other hand, the ring roller 50 is directly connected to the fixing member 60.
The float prevention roller 32 is rotatably supported by a support 32a and has an outer peripheral surface formed in a concave curved surface shape having a curvature corresponding to the surface shape of the forming drum 2, and the float prevention roller 32 is arranged so that the axial direction thereof coincides with a direction perpendicular to the axial direction of the forming drum 2.
The floating preventing rollers 32 are pressed against both end portions 71 and 72 of the tire constituent member 70 and roll on both end portions 71 and 72, so as to press portions of both end portions 71 and 72 that overlap each other in the up-down direction and peripheral areas thereof against the forming drum 2.
The zipper rollers 40 each have a cylindrical shape, and one end portion of the zipper roller 40 is supported by shaft supports 40a on both sides. Further, the zipper rollers 40 are arranged in a symmetrical manner with respect to the engagement end 73 of the tire constituent member 70 such that the respective axes of the zipper rollers 40 are inclined at a predetermined angle toward the traveling direction with respect to a straight line perpendicular to the traveling direction. Here, the zipper roller 40 is arranged such that the predetermined angle is set between, for example, 5 ° and 30 ° and such that the intersection between the two axes is positioned above the engaging end 73.
The zipper rollers 40 respectively have a plurality of projections 41 each projecting in the axial direction along opposite edge portions and formed in the circumferential direction at equal intervals and in the same number, and on the engaging end 73 side, the recesses between the projections 41 and the projections 41 are alternately arranged in the circumferential direction at the same pitch.
The above projections 41 and recesses are alternately arranged along the circumferential direction of each zipper roller 40, and some of the projections 41 of one zipper roller 40 enter between (i.e., recesses) and engage with the projections 41 of the other zipper roller 40, and thereby the zipper rollers 40 are synchronously rotated at the same speed.
Since, during the rotational movement of the zipper roller 40, the respective protrusions 41 of the zipper roller 40 abut against the end portions 71 and 72 of the tire constituent member 70 so as to press against the predetermined ranges of the respective end portions 71 and 72, and thereby pull the end portions 71 and 72 toward each other to eliminate the slack or the like of the tire constituent member, the zipper roller 40 correctly positions the tire constituent member on the forming drum 2.
Fig. 5 is a sectional view as viewed from the arrow Y-Y direction in fig. 4, and shows a state in which the disk-shaped roller 45 is mounted on the roller shaft 46 fixed to the support 45a for the disk-shaped roller 45.
As described above, the roller shaft 46 is inclined with respect to the end 71 of the tire constituent member as shown in the drawing.
Adjacent to the disc-shaped roller 45, the side pressing roller 48 is rotatably mounted via a bearing 49 on a roller shaft 48a, the roller shaft 48a being fixed to the same support 45a that supports the disc-shaped roller 45. The side pressing roller 48 has a plurality of grooves formed at equal intervals on the outer peripheral surface thereof, and the side pressing roller 48 is adjacently disposed on the right side in fig. 5, that is, on the outer side (joint end side) of the disk-shaped roller 45.
The side pressing roller 48 abuts against the lower side end 72 of the tire constituent member 70 and holds the lower side end 72 while the rolling surface 45b of the disk-shaped roller 45 abuts against the upper side end 71 of the tire constituent member 70 and extends the upper side end 71, so as to prevent the lower side end 72 from moving together with the upper side end 71.
In fig. 5, reference numeral 62 denotes an urging member such as a mechanical or hydraulic spring or the like that is fitted to the frame body 31. The frame 31 is connected to the fixing member 60 by a biasing member 62. On the other hand, as described above, the ring-shaped roller 50 is directly connected to the fixing member 60, and in a free state in which the ring-shaped roller 50 does not abut against the tire constituent member 70, as shown in fig. 3, the lower end of the ring-shaped roller 50 is positioned above a straight line connecting the lower end of the float preventing roller 32, the lower end of the zipper roller 40, and the lower end of the disk-shaped roller 45.
Therefore, when the piston rod 18P of the piston-cylinder mechanism 18 is actuated to move the fixing member 60 downward in the state of fig. 3, first, the floating prevention roller 32, the zipper roller 40, and the disk-shaped roller 45 abut against the upper side end portion 71 of the tire constituent member 70. Thereafter, the fixing member 60 is further moved downward against the urging force of the urging member 62, and when the ring-like roller 50 abuts against the end portion 71, pressure is applied to press the ring-like roller 50 into the rubber material of the end portion 71 to stop the downward movement.
With the above configuration, while the ring-shaped roller 50 pressurizes the end portion 71 by means of the pressure of the piston-cylinder mechanism 18, the floating prevention roller 32, the zipper roller 40, and the disk-shaped roller 45 pressurize the end portion 71 by means of the force against the urging force of the urging member 62 to thereby join the both end portions 71 and 72.
In this case, since the downward pressing force of the piston rod 18P directly acts on the ring-shaped roller 50, the pressing force of the ring-shaped roller 50 is larger than the pressing force of the rollers 32, 40, and 45, etc., which acts by the downward pressing force of the urging member 62.
The following describes a process of joining the end portions 71 and 72 of the tire constituent member 70 made of rubber by the joining device 1 and a manufacturing method of manufacturing the tire constituent member 70 by joining the end portions 71 and 72. The following process and the like are performed under the control of a controller (not shown).
The controller has: a microcomputer, not shown, including, for example, a Micro Processor Unit (MPU); a ROM (read only memory) that stores programs for executing various control processes; and a RAM (random access memory) that temporarily stores data to be directly read by the MPU. Further, the controller is connected with each part of the apparatus by a connecting member and controls each part connected to the controller so that each part works in association with each other for performing each joining work at a preset timing or under a preset condition.
To engage the ends 71 and 72 (see fig. 1) of the tire constituent member 70, a member such as an inner liner or the like to be arranged inside the tire constituent member 70 is first arranged on the outer periphery of the forming drum 2, and then the tire constituent member 70 is wound one turn around the outer periphery of the rotating forming drum 2 and the forming drum 2 is stopped. At this time, the end portions 71 and 72 are overlapped with each other in the up-down direction, and the engaging unit 30 is arranged at the pressing position by the moving member 10.
Subsequently, the joining unit 30 of one side (left side in fig. 3) is moved to the center portion CL of the forming drum 2 by the moving means 10. Next, upon stopping of the moving means 10, the piston-cylinder mechanism 18 is actuated to move the joining unit 30 downward so as to press the floating prevention roller 32, each of the zipper rollers 40 and the ring roller 50 against the overlapping end portions 71 and 72 (see fig. 2) of the tire constituent member 70 (as a preferable pressing condition, the pressing force of the piston-cylinder mechanism 18 is in the range of 20kgf to 140 kgf). This causes the outer peripheral portions (tip end portions of the protrusions 41) of the float prevention roller 32 and the zipper roller 40 to abut against the end portions 71 and 72 of the tire constituent member 70.
Subsequently, the moving means 10 is actuated to move the joining unit 30 in the axial direction of the building drum 2, i.e. along the joining end 73 of the tire constituent member 70. The float prevention roller 32, the zipper roller 40, the disk-shaped roller 45, the side pressing roller 48, and the ring roller 50 are pressed against the end portions 71 and 72 of the tire constituent member 70, and thus roll along the engagement end 73 of the tire constituent member together with the movement of the engagement unit 30.
At this time, the floating preventing rollers 32 roll on both end portions 71 and 72 while sequentially pressing the end portions 71 and 72, and the zipper rollers 40 inclined in opposite directions to each other roll on both end portions 71 and 72 while pulling the end portions 71 and 72 toward each other. Then, a shearing force generated by the rolling surface 45b of the disk-shaped roller 45 which is subsequently rolled acts on the upper side end portion 71 of the tire constituent member 70 to extend the end portion 71, that is, to increase the bonding area of the overlapped portion between the end portions 71 and 72. At this time, the side pressure roller 48 holds the lower end portion 72 so as to prevent the lower end portion 72 from moving together with the upper end portion 71 when the disc-shaped roller 45 extends the upper end portion 71. Subsequently, the ring roller 50 (see fig. 4) firmly presses the increased joining area between the both end portions 71 and 72 to join the end portions 71 and 72.
Preferably, a heating member (not shown) that heats the ring-like roller 50 from the inside or the outside of the ring-like roller 50 is provided. That is, the heating means is used to heat the rolling surface of the ring-like roller 50 to a predetermined temperature and maintain the temperature, thereby softening the rubber in the vicinity of both end portions 71 and 72 of the tire constituent member 70 at the pressurized (rubbed) position, which increases the joining effect of the ring-like roller 50 between both end portions 71 and 72 to allow the end portions 71 and 72 to be joined with high joining strength.
In the manner described above, the engagement of the tire constituent members is performed to some extent by the engagement device 1 on one side, and then the piston-cylinder mechanism 18 on the other side is actuated to move the engagement unit 30 (on the right side in fig. 3) downward to the vicinity of the central portion CL of the forming drum 2. However, the lowered position is set to a position where the engagement by the engaging unit 30 on the left side has been completed, and the engaging unit 30 on the right side is moved from the lowered position in a direction opposite to the traveling direction of the unit 30 on the left side. That is, the pair of joining units 30 are moved outward in the axial direction of the forming drum 2 in opposite directions to each other at the same speed so that each of the rollers 32, 50, the zipper roller 40, and the disc-shaped roller 45 rolls along the end portions 71 and 72 to join the entire end portions 71 and 72 in sequence.
Fig. 6 is a perspective view showing the end portions 71 and 72 of the tire constituent member 70 thus joined together. The tire constituent member 70 is joined in a state where the end portion 71 is extended to increase the joining area.
An unvulcanized tire having a predetermined shape and structure may be molded such as by arranging another tire constituting member on the joined tire constituting member 70, and various types of tires may be manufactured by vulcanizing and molding the unvulcanized tire.
Embodiments of the present invention have been thus described. In the present embodiment, the disk-shaped roller 45 is combined with the float prevention roller 32, the zipper roller 40, the ring-shaped roller 50, and the side pressure roller 48 to constitute the joining unit 30 so that the traveling direction associated with rolling is restricted to ensure straightness, thereby enabling stable operation.
Although the embodiment of the present invention has been described using the joining device that joins the tire constituent member 70 on the forming drum 2 as an example, the use of the joining device 1 allows the joining of the tire constituent member 70 to be performed equally even on a support other than the forming drum 2, such as a flat support or a conveyor belt.
Next, the results of experiments conducted on a product obtained by joining with the joining apparatus according to the present invention and a conventional product obtained by joining with a conventional apparatus will be described using a carcass ply as an example of a tire constituent member.
Fig. 7 is a graph showing the tensile strength of the product of the present invention and the tensile strength of the conventional product when a carcass ply formed by joining the ends of the carcass ply on a building drum is pulled with the same tensile force by the relationship between the extension of the interval between cords embedded in the carcass ply and the adhesion range of the joining portion (the length in the axial direction of the building drum).
In the graph, O represents a conventional product, and x represents a product of the present invention.
Fig. 8 is a schematic diagram showing comparison of states before and after stretching by passage of a carcass ply as a conventional product and a carcass ply as a product of the present invention, respectively.
As is apparent from fig. 7 and 8, the product of the present invention has a larger engagement range and a smaller interval between the cords C after pulling, compared to the conventional product. That is, the product of the present invention is superior to the conventional products in tensile strength.
As a result of the experiment, it is preferable to set the overlapping width between the upper end portion 71 and the lower end portion 72 of the tire constituent member 70 used in the present embodiment to be in the range of 0.1mm to 10 mm. When the overlapping width falls within the above range, the effect obtained by extending the upper side end portion 71 with the present joining-purpose joining apparatus is remarkable. When the lamination width is less than 0.1mm, the absolute value of the lamination width is small at first, so that the effect obtained by extending the upper side end portion is limited. On the contrary, when the overlapping width exceeds 10mm, the absolute value thereof is large, and thus a required engaging force can be obtained from the overlapping width itself, so that the effect is limited.
